# Solar eclipse of April 17, 1996

A partial solar eclipse occurred at the Moon's descending node of orbit between Wednesday, April 17 and Thursday, April 18, 1996, with a magnitude of 0.8799. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
A partial eclipse was visible for parts of Antarctica, New Zealand, and eastern Oceania.

## Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
Eclipse season of April 1996 :
| April 4 Ascending node (full moon) | April 17 Descending node (new moon) |
| Total lunar eclipse Lunar Saros 122 | Partial solar eclipse Solar Saros 148 |

### Solar eclipses of 1993–1996

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.
Solar eclipse series sets from 1993 to 1996 :
| Descending node | Descending node | Descending node | Ascending node | Ascending node | Ascending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 118 | May 21, 1993 Partial | 1.1372 | 123 | November 13, 1993 Partial | −1.0411 |

### Saros 148

This eclipse is a part of Saros series 148, repeating every 18 years, 11 days, and containing 75 events. The series started with a partial solar eclipse on September 21, 1653. It contains annular eclipses on April 29, 2014 and May 9, 2032; a hybrid eclipse on May 20, 2050; and total eclipses from May 31, 2068 through August 3, 2771. The series ends at member 75 as a partial eclipse on December 12, 2987. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
The longest duration of annularity will be produced by member 22 at 22 seconds (by default) on May 9, 2032, and the longest duration of totality will be produced by member 54 at 5 minutes, 23 seconds on April 26, 2609. All eclipses in this series occur at the Moon’s descending node of orbit.
Series members 10–31 occur between 1801 and 2200: :
| 10 | 11 | 12 |
| December 30, 1815 | January 9, 1834 | January 21, 1852 |

### Metonic series

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's descending node.
22 eclipse events between September 12, 1931 and July 1, 2011 :

### Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.
The partial solar eclipses on December 7, 2170 (part of Saros 164) and November 7, 2181 (part of Saros 165) are also a part of this series but are not included in the table below.
Series members between 1801 and 2105 :
| September 28, 1810 (Saros 131) | August 27, 1821 (Saros 132) | July 27, 1832 (Saros 133) | June 27, 1843 (Saros 134) | May 26, 1854 (Saros 135) |
| April 25, 1865 (Saros 136) | March 25, 1876 (Saros 137) | February 22, 1887 (Saros 138) | January 22, 1898 (Saros 139) | December 23, 1908 (Saros 140) |
| November 22, 1919 (Saros 141) | October 21, 1930 (Saros 142) | September 21, 1941 (Saros 143) | August 20, 1952 (Saros 144) | July 20, 1963 (Saros 145) |
| June 20, 1974 (Saros 146) | May 19, 1985 (Saros 147) | April 17, 1996 (Saros 148) | March 19, 2007 (Saros 149) | February 15, 2018 (Saros 150) |

### Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
Series members between 1801 and 2200 :
| August 16, 1822 (Saros 142) | July 28, 1851 (Saros 143) | July 7, 1880 (Saros 144) |
| June 17, 1909 (Saros 145) | May 29, 1938 (Saros 146) | May 9, 1967 (Saros 147) |
